WSL hangs after sleep

[claremont-awilson]

Windows Version

Windows 10.0.19041.5848

WSL Version

2.4.13.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

No response

Distro Version

Oracle Linux 9.2

Other Software

I've got Hyper-V feature enabled.
Docker Desktop installed.

Repro Steps

Open WSL2, let computer go to sleep, wake up - vscode can no longer connect to WSL2, any existing WSL2 terminal window will continue to work, but cannot open a new one.

Expected Behavior

I expect WSL2 to open

Actual Behavior

It hangs

Whilst researching this issue, I encountered #10710. I found a process with an associated vhdx handle and I killed it (NB this is a bad idea, it blue-screened my laptop).

Once my laptop booted back up, WSL was working fine again.

Then, I've went away for an hour and my laptop must have went to sleep.

Vscode could no longer connect to WSL:

An existing WSL window is open, and I can interact with it fine. If I try to open another WSL window I get an error:

Catastrophic failure
Error code: Wsl/Service/E_UNEXPECTED

[process exited with code 4294967295 (0xffffffff)]
You can now close this terminal with Ctrl+D, or press Enter to restart.

I've generated new diagnostics logs.

Interstingly the Oracle Linux 9.2 image is the one having an issue (my default), if I launch OL7.9 it works fine and same with Ubuntu 24.04...

Although that wasn't true when it was hanging, they didn't launch either. I feel my issues are 2-fold...

Just realised the dmesg output may be useful from the still running OL9.2 image:

I am experiencing a similar issue. In my case, wsl will lose connection 2-3 times per day, even while actively being used.

Windows Version
Version 10.0.22631 Build 22631

WSL Version
2.5.7.0

Are you using WSL 1 or WSL 2?
WSL 2

Distro Version
Ubuntu 24.04.2 LTS

Other Software
Docker Desktop installed.

Repro Steps
I Work as usual, and am interrupted by a fatal error, causing vscode to disconnect from WSL. I also cannot connect to the Ubuntu command line directly.

Expected Behavior
I expect WSL2 to open

Actual Behavior
It hangs

It's been a couple of weeks. Is there anything we can provide to assist with diagnosing the issue?

[addlatt]

I think the issue is related to, if not duplicate of, #12991 .
I was able to fix by disabling resource saver: settings > resources > advanced > resource saver.

There is a greater underlying issue, but i have been crash free with this workaround.

[YingcaiDong]

A temporary fix. When WSL freezes, open PowerShell in administrator mode, and run this command

tasklist /svc /fi "imagename eq svchost.exe" | findstr LxssManager
